The present invention relates broadly to material handling apparatus, and. more particularly to apparatus of this character adaptable for use in mills and the like hano dling slabs billets, strips or other shapes or bodies which it is desired to store or pile in predetermined places or piles While the invention is particularly useful in iron and steel mills for the handling heavy shapes,

m the utility of the invention is. not lirriited in this respect,

lumauy cases it is desirable to transfer shapes directly from a roll table or other carrier to cradiesprovided for their receptioii, the cradles being locsted diiiereiit distances from the cerriern In many mills it has been customary heretofore to utilize cranes, slices or similar equipment for this "purpose. The manual attention required. as $9 well as the objection to overhead equipment by. reason of danger, have constituted inhererit objection to such installations The present invention hes for one of its obgects the provision of transfer mechanism selectivelv o eralole. iii the general horizontal plane he carrier for engaging shapes on the carrier and delivering the same at will to predetermined cradles or price at varying distances from the carrier, cally. therefore, the present apparetoe may be referred to as a selective piler.

In the accompanyin drawings there is shown for purposes 0 illustration only, a preferred embodiment of the present mvention, it being understood that the drawings do not define the limits of my inveutiou as changes in the construction and operation disclosed therein ma be made without departing either from he spirit of the present invention or the scope of my broader claims.

in carrying out the present invention there may be provided a carrier 2 illustrated here in as comprising a roll table having a line shaft 3 for driving the rolls tlriereoi'f in the direction and at the speed desired Disposed at one side of the carrier is a series of stands 4 constructed to form cradles A, B (3. and B respectively at difiereut perdetermiiied distances from the carrier, and into which it is desired to selectively pile-bodies from the carrier, Each of the cradles may have cushioning means 5 therein formed by blocks of wood or other suitable material,

On the side of the carrier oppositethe cradles are supports 6 carrying spaced angles 7 constituting elongated-guides for slides 8, there being a series of supports and a pair of guides for each slide. Each slide'is preferably constructed of side angles ii connected at their upper edges by a channel beam 10, the sides of the channel extending between and definitely spacing the angles. Movably mounted for limited sliding movement within each of the slides is a rack bar 11 having its teeth projecting downwardly through the bottom of its slides between the side angles 9.

Adjacent the inner ends of the guides 7, there is secured to each pair of guides a drag, each comprising a yokef12 extending around and below the guides and projecting upwardly beyond the edges thereof" Exd at their undersides against the channels 10 'are shoes 13 held downwardly against by springs 14 carried by bolts 15 having nuts 16 by means of which the pressure on the springs may be varied at The ends of the ahoes lfl preferably extend between lugs 18 formed on the-up- I standing euds of the yokes 12 and projecting:

tit

ilk

upwardly therefrom, thereby holding the initially hold the same against movement until such time as the drive thereon becomes positive, and thereby efi'ective for overcomingthe friction of the shoes.

Secured to the inner end of each of the rack bars 11 is a dog-carrier 19, preferably shaped to partially inte'rfit with its rack bar, as clearly shown in Figure 5, and bolted 1n position thereon. generally of trough-shaped construction having their bottoms shaped to slide on the guide angles 9 of theslides, and having their openings disposed upwardly. The sides of the dog carriers are formed with elongatedopenings 20 adapted to receive pivot pins 21 carried by the angles 9 and extending transversely through the carriers, the angles 9 being provided with hearing plates 22 for the pins.

Loosely mounted on each of the, pins 21 is a dog 23 having a tail 2% of such weight that the dogs normally tend to assume the.

full line position of Figures 5 and 6 as soon as they are released. From Figures 3 and 5 it will be apparent that the channels 10 of the slides terminate at apoint sligl'utly ahead of the drags, but that the side angles 9' continue "forwardly to form hearings for the pivot pins 21. Projectin upwardly from the bottom of the trough 0? each of the dog carriers is a lug 25 having its rear end inclined and adapted to engage a projection 26 on its corresponding dog. By reason of this construction, it will be apparent that upon movement of any dog carrier to the left, as viewed in Fi ure 5, or from its -lull line position oi this hgure to its dotted line position, relativel' to its slide,'the lug 25 will engage the projection 26 on the dog and swing the dog to its dotted line position, while upon similar relative movement in theopposite direction the dog will assume its normal full line position. This relative movement continues until one end or the other of the elongated openings 20 enga es their cooperating pin 21, and is insured the holding action oi the drag on the slide. permitting the raclr bar to move initially relatively thereto until positive drive is transmitted through the pivot For producing the desired movement rack bars ii there is. provided a drive shor 2'? journaled in suitahle bearings 28, provided between each pair oi hearings with a 29 eshing tuna the of one of reel; The drive shaft be driven in any d sired manner, as for example by o; motor 38. order prevent tilting of the slides and hers, and disengagement or? the rack bars from I their driving gears, the bearings 28 are core tinned upwardly to accommodate rolls 33.,

These dog carriers are neszsao moving all of the rack bars to the right, rela= lively initially to the slides. Upon the commencement of this movement, the dogs will drop to their normal position ready to engageany body on the carrier.

forwardly below the plane of delivery of the carrier, ready to receive and support such body when transferred from the car rier. "When this relative movement has continued to an extent suihcient to bring the ends of the openings QOinto engagement with the pins, a positive drive will be transmitted to the slides, thereby moving the slides and rack bars concomitantly to the left as viewed in Figure l, and to the right as shown in Figures 2, 3 and 5. This movement as continued will bring the dog-carriers over the respective cradles, the overhanging portions of the slides successively engaging the stands 4, and being supported thereby. l Vhen the dog-carriefsare in position over the desired cradles, rotation oi the drive shaft 27 will be reversed, thereby effecting an initial movement of the rack bars in the opposite direction relative to the slides. Durin this movement the dogs will engage the bodies on the dog-carriers and prevent movement thereof with the rack bars. Thus, gradually, the dog carrierswill be withdrawn fromsupporting relationship to the bodies, and they wi l fall into the desired cradle. Continued relative movement will effect a swingingmovement off the dogs to their dotted line position, whereby they are free to pass under bodies on the carrier during the return movement of the slides and rack bars. This return movement will occur just as soon as the pins are engaged by the slots and the friction of the drag thereby overcome. The operation may be repeated as often as desired and successive bodies deliver-ed to desired position or distance From the carrier.

At the same time, the dogcarriers will gradually move referred to operable for selectively delivering and piling successive bodies at any one of a lu 'ality of selectedpositions.
